The purpose of this environmental assessment was to research the past and current use of the subject site and adjacent properties and identify any environmental concerns with the potential to impact the subject property. Based on a review of historical sources, the Phase I Property appears to have never been developed. The northern and eastern portion of the site have been paved for parking or an access lane associated with the adjacent residential apartment building to the north, which was developed at some time between 1969 and 1974. Based on a 1968 site plan provided by the client for review, an underground oil storage tank may have been present on the northeastern portion of the Phase I Property. Surrounding properties were historically used for agricultural purposes, until residential development occurred on the north side of Walkley Road in the 1960’s, followed by additional development with commercial and or institutional properties on either side of Walkley Road, in the 1970’s. Other than the aforementioned potential UST, no on-site PCAs or off-site PCAs with the potential to result in an APEC on the Phase I Property, were identified during the historical review. Following the historical review, a site visit was conducted. The Phase I Property is partially paved as described above, while the remainder of the site is landscaped. The southern portion of the subject land is slightly above the grade of Walkley Road and the eastern portion of the site slopes down to the north. Vent and fill pipes indicating a potential UST were identified along the south wall of the adjacent apartment building to the north, resulting in an APEC on the northeastern portion of the Phase I Property (it has since been confirmed that the UST was removed). No other PCAs were identified on the subject site at the time of the site visit. At the time of the site visit, the current use of the adjacent and neighbouring properties within the Phase I ESA Study Area were observed from publicly accessible areas. No off-site PCAs with the potential to impact the Phase I Property were identified at the time of the site visit. Report: PE4234-1 April 2, 2018 Page ii paterson group Phase I – Environmental Site Assessment Ottawa Kingston North Bay Part of 2190 Halifax Drive - Ottawa Conclusion Based on the results of the Phase I ESA, a Phase II Environmental Site Assessment is recommended for the Phase I Property. A Phase II ESA has since been completed and is provided under separate cover. Report: PE4234-1 April 2, 2018 Page iii paterson group Phase I – Environmental Site Assessment Ottawa Kingston North Bay Part of 2190 Halifax Drive - Ottawa 1.0 INTRODUCTION At the request of Urbandale Corporation (Urbandale), Paterson Group (Paterson) conducted a Phase I - Environmental Site Assessment (Phase I ESA) for a parcel of land along the north side of Walkley Road, west of Halifax Drive, in the City of Ottawa, Ontario. The subject land forms part of a larger parcel of land addressed 2190 Halifax Drive. The purpose of this Phase I ESA was to research the past and current use of the site and study area and to identify any environmental concerns with the potential to have impacted the subject property. Paterson was engaged to conduct this Phase I ESA by Mr. Roger Tuttle of Urbandale Corporation. Mr. Tuttle can be reached by telephone at (613) 731- 6331. This report has been prepared specifically and solely for the above noted project which is described herein. It contains all of our findings and results of the environmental conditions at this site. This Phase I ESA report has been prepared in general accordance with the requirements of Ontario Regulation 153/04 as amended by O.Reg. 269/11 (Environmental Protection Act), and also complies with the requirements of CSA Z768-01. The conclusions presented herein are based on information gathered from a limited historical review and field inspection program. The findings of the Phase I ESA are based on a review of readily available geological, historical and regulatory information and a cursory review made at the time of the field assessment. The historical research relies on information supplied by others, such as local, provincial and federal agencies and was limited within the scope-of-work, time and budget of the project herein.
